Was the WebUI implementation from "4.23 - Remote Control Over HTTP" ever released?

I’m referring to the Web page presented in this video. Was this even released publicly?

Same question here. We found the web control plugin, but how do we get a website like in the video with those standard components setup? Is there an example? Right now it looks like we would need to write a website to control Unreal completely from scratch.

Any way to access these standard components as a baseline like in the video?
